FRAME BUILDING DISMANTLING TOOL Filed Feb. 6', 1950 3522 we mz mwc/Patented Jan. 1, 1?52 BUILDING DISMANTLIN TOOL Henry Phillip Fchler,Wolseley, Saskatchewan, Canada Application February 6, 1950, Serial No.142,586

4 Claims. (01. 254431) My invention relates to dismantling tools, havingparticular reference to an all purpose tool for use in wrecking framebuildings.

In the art to which the invention relates it has been proposed toprovide wrecking bars and other tools for removal of boards, studdingand the like in the dismantlingof frame buildings. In such devices noprovision is made for application of a uniform pressure acrossthe fullwidth of the part being removed, such as a board, to avoid splitting theboard or breaking it. 1

The present invention'contemplates improvements in frame buildingwrecking and dismantling tools by provision of means for application ofuniform pressure over the whole face of a board or the like that isnailed to another part of the building from which it is to bedisengaged. The tool further provides an adjustable attachment by whicha limitation may be imposed on the extent to which a board orthe like ispried loose from a stud, and a further attachment by which applicationof the tool may be limited to one board at a time.

One of the objects of the invention is accordingly to provide animproved frame building dismantling or wrecking tool adapted forapplication of pressure to the full width of a board or the like indisengaging the board from a part to which it is nailed.

A further object of the invention is to provide in a buildingdismantling tool means by which a limitation may be imposed on theextent of disengagement of a board or the like from a part of thebuilding to which it is nailed.

'A still further object of the invention is to provide in a dismantlingtool adjustable means by which pressure applied by the tool indisengaging a board or the like from a part to which it is nailed may belimited to a single board.

Qther features and advantages of the inventionwill become apparent byreference to the accompanying description taken in conjunction with thedrawings wherein like characters of reference indicate like partsthroughout the sev eral views and wherein:

Fig. 1 is a side view of a tool embodying my improvements and shownpartly sectioned.

Fig. 2 is a detail view of the heel plate with fragment of the pressureapplying arm.

Fig. 3 shows a side view of the width adjuster attachment taken byitself.

Fig. 4 shows a detail view of the depth adjusting attachment taken byitself.

Fig. 5 shows a side view of the tool complete as it would appear in use,with fragments of boards and stud included.

Having reference to the drawing my improved frame building dismantlingtool provides a tubular handle bar I with pressure applyingarm 2fixed-thereto at an acute angle to the handle bar and a brace member 3between the arm 2 and bar I, the brace member attaching in right angularrelation to the pressure applying arm.

At the junction of the handle bar I and pressure applying arm 2 is aheel plate 4 fixed thereto and providing chisel points 5-5 projectinglaterally of the handle bar and pressure applying arm, the chisel pointsproviding flat faces, asat 6, lying substantially on a line with theunder surface of the pressure applying arm.

The tool may be used without the attachments, to be hereinafterdescribed, and as above described may be applied in the dismantling of abuilding. The tool has a variety of uses and methods of application tomeet the various problems presented in disengaging parts of the build:ing nailed to other parts, as will readily suggest itself to one skilledin the art.

In the simple application of the tool the one or other chisel point 5 isengaged behind a stud, such as the stud l illustrated in Figure 5, andwith the arm 2 lying substantially flat against a board 8 to bedisengaged, or, as in a starting series of boards, a chisel end of theheel may be driven between a board and its stud. By pressure on thehandle I in the direction indicated by the arrows the board 8 may bepried from the stud 1. The pressure exerted on the arm 2 is across theface of the board eliminating danger of splitting the board.

In the use of the tool it is generally desirable to pry a board onlypartly oil until the board has been similarly disengaged from the nextstud, particularly where the studding is closely spaced. For this Iprovide a depth limiting attachment, separately illustrated in Figure 4.

This consists of a short piece of angle plate 9 engaged on the bracemember 3 by a U clamp ID, with an insert H interposed between the clampand member 3. The clamp is secured to the angle plate 9 by nuts l2threaded on the legs of the clamp, by which the clamp may be loosened toshift the angle plate along the member 3 and attach it at such distancefrom the arm 2 as is required.

Referring again to. Figure 5, when the board 8 has been pried loose asfar as is desirable on that application of the tool, the angle plate 9coming in contact with the stud stops further downward pressure of thearm 3 fulcrumed on the heel plate 4. At this stage the tool may beapplied at the next stud, or the nails removed from the stud from whichthe board is partially disengaged.

It has further been found desirable to limit application of the arm 2 toone board at a time. For this I provide a width adjuster, separatelyillustrated in Figure 3. This consists of a bar l3 bent U-shaped at oneend, as at M, with clamping bolt i 5 having a nut l6 by whieh the Uportion of the car may be secured frictionally in any desired positionof adjustment along the arm 2. At the other end of the bar 13 is a bentfinger ll engageable loosely in a suitable opening in the tubular handleI, the end portion [8 of the finger lying within the bore of the handle.

In the use of the adjuster bar 13, the bar is set with the U portion I4fixed to the arm 2 a distance from the free end 6f the arm 2 nor.-responding to the width of the board ii so that pressure of the arm 2will apply to the board only. lnl' figure 5 a partially removed board [9is also WP- .t I r r s re is further included a point 20 for the freeend 01 the h' -ndle 1;, this point being ja sep arate element andremovable, and including a shank '2! of reduced -dian'let'er insertahlein the bore of'the tubuiarhandle. Ifhis permits reversing the tool touse the pointed end for prying he u d- ,.Y

While I have herein disclosed a preferred'embodirn'e'nt of my invention,changes in the construction and arrangement of parts would beconceivable, and in so f r as such changes come within the spirit andscope or the invention as defined in the appended claims they would beconsidered 'a parthereof. v

Having thus particularly described and ascertained thefnature of myinyention, what I claim and wish to secure by Letters Patent is:

1. A frame building dismantling tool providing a handle with pressureapplying arm fixed there- "to at one end thereof at an'acute angle inrelation to the handle, and a heel plate at the junction of said arm andhandle, fixed to the outer side extending transversely thereof andprojecting outwardly on both sides of the handle and pressure applyingarm, said heel plate having tapered end portions terminating insharpened edges.

2. A frame building dismantling tool comprising a handle, a pressureapplyingarm fixed to the handle at one end thereof at an acute angle inrelation to the handle, a brace member betweenthe pressure applying armand handle, and a heel plate at the junction of said arm and handle,fined to the outer side extending transversely thereof and projectingoutwardly on both sides of p the handle and pressure applying arm, saidheel plate having tapered ends terminating insharpened edges.

'3. A device as defined in claim 2 and includinga depth adjustingattachment, comprising a plate withnieans attaching the plate on thebrace member projecting laterally thereof, said means being adjustablelengthwise on the brace r-,,, u e

4. A device as'deiined in claim 2 and including a width adjustingattachment comprising a bar with means onthe bar deta'chabl yeng'agingthe handle, said bar providing a U bent portion ehgaging thepressure applying arm andmeans for clamping the U bent portion to thepressure applying arm adjust ble thereon.
